Anyone else sick of it all and wishes they could switch it off

OH I understand the poster. I'm in a wonderful relationship with my gf...its what I want. The sex, the coupledom is brilliant etcetcetc. But I also sometimes crave man to man sex....cock....that meeting of two guys who just want to release and share a man to man experience. Nothing heavy, just that mutual sensual passionate experience of same sex sex if you like. I don't often act on it, but when I do its in secret (yes safe sex) and in a funny way it makes it even more exciting and I realise that what I'm releasing is something my gf can't give me for that moment. Otherwise everything else with her is so fulfilling. So am I wrong to occassinally like a custard cream cake when I mostly prefer a strawberry one? I like them both...but one more than the other. So therefore I have my custard cake in secret, which is fine. However...I wish sometimes I hated custard!!!!
